Listed building consent drawings for Wilton — measured as existing, proposed in the same detail, and supported by a heritage statement that answers Wiltshire Council's conservation officer on the terms the 1990 Act actually sets.
Wiltshire Council granted 96% of the householder planning decisions it made in its latest published year — 9 points above the 87% England-wide householder average. Wilton contains NETHERHAMPTON, WILTON conservation areas (NETHERHAMPTON designated 1984), so materials, fenestration and roof form are assessed against the appraisal, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901) and postwar (1945–1970) housing stock sets the design brief on most streets.
The permitted-development ceilings are fixed: 40m³ of new roof volume for a terraced loft and 50m³ for a semi or detached house under Class B, plus a 3m single-storey rear extension on a terrace or 4m on a detached house under Class A. Wilton carries at least one Article 4 direction, and conservation areas including NETHERHAMPTON and WILTON remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Wilton is determined against an 8-week statutory target.
NETHERHAMPTON (conservation area designated in 1984), WILTON (conservation area designated in 1973), Quidhampton (civil parish within Wilton) and Netherhampton (civil parish within Wilton) — these are the Wilton pockets our drawings cover most. Heritage designations here include NETHERHAMPTON and WILTON. Wiltshire Council weighs each proposal against Wiltshire Council's adopted local plan and its householder design guidance, where the 2,440 homes here are 23% pre-1900, 16% 1955-1964, 9% 1973-1982, which is what sets the realistic roof and rear-projection options. On roofs the borough is steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building, over Victorian and earlier houses (23% of 2,440 homes), late-1950s and early-1960s houses (16%) and 1970s and early-1980s houses (9%).
Before anything is drawn we check your address against the designations that apply in Wilton: NETHERHAMPTON (conservation area designated in 1984) and WILTON (conservation area designated in 1973). Inside those boundaries permitted development is curtailed and Wiltshire Council assesses materials, window detail and roof form against the area's own appraisal, so a scheme that would be waved through two streets away can need a full application here.
Beyond the designated areas, Wilton takes in Quidhampton and Netherhampton. Wiltshire Council has 48 recorded Article 4 directions, removing permitted development for rear and side extensions and other roof alterations, including rooflights — check the address before assuming PD applies in Wilton.
On stock, Wilton is Victorian and earlier houses (23% of 2,440 homes), late-1950s and early-1960s houses (16%) and 1970s and early-1980s houses (9%) — which is why steeply pitched slate roofs, valley gutters and party parapets typical of pre-1900 building and shallow gabled roofs typical of that period's building govern what a loft or rear projection can realistically be. Wiltshire Council decided 1,779 householder applications in the latest published year and granted 96%, with 53% issued inside the eight-week target. That decision record, not a national figure, is what we design to.
The full build-period split for Wilton runs pre-1900 23% (550 homes), 1900-1918 3% (80 homes), 1919-1929 4% (100 homes), 1930-1939 4% (90 homes), 1945-1954 7% (180 homes), 1955-1964 16% (390 homes), 1965-1972 5% (130 homes), 1973-1982 9% (230 homes), 1983-1992 3% (70 homes), 1993-1999 5% (110 homes) and 2000-2008 3% (70 homes). That distribution is why pre-1900 detailing dominates the drawings here, and it is measured from council-tax records rather than assumed from the street name.
Wiltshire Council also decides for Aldbourne & Ramsbury, Amesbury West, Avon Valley, Box & Colerne, By Brook, Corsham Ladbrook, Corsham Pickwick and Corsham Without, so a decision in Wilton sits inside a wider pattern of decisions we track across the same authority — useful when an officer cites a precedent from the next area over.
The Article 4 directions recorded for this council include Ashley, Avebury, Baydon 1 and Baydon 2. Each removes a specific permitted-development right inside its own boundary, which is why the check is done on the address rather than on the town.

Listing protects the whole building, not the front elevation. Removing a partition, replacing a staircase balustrade, changing a floor finish, or lining a wall with insulation are all alterations to special interest, and all can require consent. That surprises owners far more often than the external rules do — and it is why the first deliverable on a listed project is an accurate record of what is there, not a proposal for what replaces it.
Wilton sits within an area of Victorian and earlier houses (23% of 2,440 homes), late-1950s and early-1960s houses (16%) and 1970s and early-1980s houses (9%), and its designated heritage includes NETHERHAMPTON and WILTON. Conservation-area designation and listing are different things and frequently overlap: a listed house inside a conservation area needs consent for internal work under the listing, and is judged on its contribution to the wider area under the designation. We establish both before proposing anything.
Section 16(2) of the 1990 Act requires Wiltshire Council to have special regard to the desirability of preserving the building, its setting and any features of special architectural or historic interest. In practice that means the drawings must show what is being lost as clearly as what is being gained, and the case for the intervention must be made on heritage terms rather than on convenience.
Consent from Wiltshire Council is required for works affecting special interest. That commonly includes:
We survey the building as existing at a level of detail that lets a conservation officer see the fabric, then draw the proposal in the same detail alongside a heritage statement — so the decision is made on evidence rather than on assumption.
Below is Wiltshire Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Wiltshire Council granted 96% of its householder applications in the year to 31 March 2026, and NETHERHAMPTON shapes what is approved here. Listed applications are decided on the quality of the record and the justification, which is where most refusals actually originate.

Across NETHERHAMPTON, WILTON and Quidhampton, the schemes that get consent tend to be reversible, legible and honest: new work that reads as new rather than as imitation, services routed in existing chases rather than cut into original fabric, and interventions concentrated in later or lower-significance parts of the building. Rear additions in a contemporary idiom are often accepted where a pastiche extension is refused.
Wilton contains NETHERHAMPTON, WILTON conservation areas (NETHERHAMPTON designated 1984), so materials, fenestration and roof form are assessed against the appraisal. Where planning permission is needed as well — for an extension, say — the two applications run in parallel and are usually determined together. We prepare them as a single coordinated set so the heritage case and the planning case do not contradict each other, which is a surprisingly common reason for a refusal on an otherwise sound scheme.
We prepare listed building consent packs across Wilton. A few of the areas where heritage work comes up most often:
Listed building consent drawings for NETHERHAMPTON — conservation area designated in 1984 — surveyed as existing and drawn to the detail Wiltshire Council's conservation officer needs.
Listed building consent drawings for WILTON — conservation area designated in 1973 — surveyed as existing and drawn to the detail Wiltshire Council's conservation officer needs.
Listed building consent drawings for Quidhampton — civil parish within Wilton — surveyed as existing and drawn to the detail Wiltshire Council's conservation officer needs.
Listed building consent drawings for Netherhampton — civil parish within Wilton — surveyed as existing and drawn to the detail Wiltshire Council's conservation officer needs.
They are separate consents with different tests, and many projects need both.
| Consent | What it covers | Fee | Consequence of proceeding without it |
|---|---|---|---|
| Listed building consent | Works affecting special interest, internal and external | None | Criminal offence under section 9 of the 1990 Act |
| Planning permission | Development — extensions, outbuildings, use changes | Payable | Enforcement action; may become immune after 10 years |
| Conservation area consent context | Demolition and character in a designated area | Varies | Enforcement; prosecution for unauthorised demolition |
| Building regulations | Structure, fire, insulation, ventilation | Payable | Enforcement notice; problems on sale |

A process built around what a conservation officer actually assesses.
Send us the address and the listing entry. We confirm grade, what the listing covers, whether curtilage structures are caught, and how Wiltshire Council has treated comparable schemes.
We survey as existing in real detail — plans, elevations, sections and the features that carry the significance — because a proposal cannot be assessed against a record that does not exist.
We draw the proposal in matching detail and write the heritage statement that identifies significance, impact and justification in the terms section 16(2) requires.
We submit to Wiltshire Council, engage with the conservation officer, and revise the drawings free until the decision is issued.
Frequently, yes. Listing covers the whole building, so removing a partition, altering a staircase, replacing joinery or re-plastering historic surfaces can all require consent from Wiltshire Council. There is no internal exemption and no size threshold. The safe route is to establish what is significant before work is designed, which is what the measured survey is for. This applies to your Wilton address specifically.
Carrying out unauthorised works to a listed building is a criminal offence under section 9 of the Planning (Listed Buildings and Conservation Areas) Act 1990, and it does not become lawful with the passage of time the way some planning breaches do. Wiltshire Council can require reinstatement. Where work has already happened, an application for retrospective consent is usually the right first step, and we can advise on it. This applies to your Wilton address specifically.
No. Listed building consent applications carry no application fee, which sometimes leads owners to assume the process is lighter than a planning application. It is not — the evidence expected is greater, because the decision rests on the effect on special interest rather than on amenity, and an under-documented submission is the most common cause of delay. This applies to your Wilton address specifically. Wiltshire Council is the decision-maker.
If the work is also development — an extension, an outbuilding, a change of use — then yes, and the two applications run in parallel to Wiltshire Council. Internal alterations usually need only listed building consent. Where both are required we prepare them as one coordinated set, because inconsistencies between the two submissions are a recurring reason for delay. This applies to your Wilton address specifically.
Sometimes, but rarely with modern units. Historic windows are often the single most significant surviving feature, and replacement is judged on the condition of the existing joinery and the accuracy of what replaces it — glazing bar profile, glass type, opening method and reveal depth all matter. Repair and secondary glazing are usually the route that gains consent, particularly inside designated areas such as NETHERHAMPTON and WILTON. This applies to your Wilton address specifically. Wiltshire Council is the decision-maker.
The statutory target is eight weeks from validation for most applications, and thirteen for larger schemes. In practice the timetable is set by how complete the submission is: a conservation officer who has to ask what the existing fabric looks like will take longer than one who can see it. We submit a record that answers those questions upfront. This applies to your Wilton address specifically. Wiltshire Council is the decision-maker.
